Criticare care

Ingrid Dannevig, Helen Caroline Dale, Knut Liestøl, Rolf Lindemann
AIM: To compare blood pressure in neonates obtained from three different oscillometer blood pressure monitors (Dinamap, Criticare, Hewlett-Packard) with arterial blood pressure (Hewlett-Packard' invasive unit). STUDY DESIGN: A total of 32 randomized, non-invasive blood pressure series, each consisting of three measurements from each monitor, were obtained from 20 neonates (birthweight 531-4660 g). Each measurement was compared with the invasive pressure. RESULTS: Two factors appear to have a systematic effect on the difference between oscillometric and invasive pressure (the measurement deviance): the size of the infant, e...

Respiratory monitoring is an important aspect of critical care, especially in neurosurgery and neuro-intensive care. Fixed capnographs are too cumbersome to allow monitoring during patient transport. Recently several portable expired fraction carbon dioxide devices have been developed, but no evaluation of their clinical peformance has been reported. We compared the Criticare POET LT Handheld expired fraction carbon dioxide monitor, in three different settings, to fixed capnographs and arterial blood gas analysis...

STUDY OBJECTIVE: To determine the effect of a new pulse oximeter (Nellcor Symphony N-3000, Pleasanton, CA) with signal processing technique (Oxismart) on the incidence of false alarms in the postanesthesia care unit (PACU). DESIGN: Prospective study. SETTING: Nonuniversity hospital. PATIENTS: 603 consecutive ASA physical status I, II, and III patients recovering from general or regional anesthesia in the PACU. INTERVENTIONS: We compared the number of alarms produced by a recently developed "third"-generation pulse oximeter (Nellcor Symphony N-3000) with Oxismart signal processing technique and a conventional pulse oximeter (Criticare 504, Waukesha, WI)...

Four commercially available pulse oximeters were compared on normal infants to determine incidence and correct identification of movement artefact, and to assess their other features, in order to guide the potential user in the most appropriate choice of a machine to suit their purposes. Measurements of arterial oxygen saturation by pulse oximetry are distorted by movement artefact. During five one hour recording periods, over 100 artefacts occurred with each machine. The incidence of movement artefact differed between oximeters...

Four pulse oximeters and two pulse oximeter-capnographs were evaluated on accuracy of measuring oxygen saturation and heartrate for the former and oxygen saturation, heartrate, respiratory rate and capnography for the latter. In the first part of the study four pulse oximeters (Criticare Systems Model 501 +, Ohmeda Biox 3700 Pulse Oximeter, Nellcor Model N 100 and Datex Satlite) were simultaneously studied on 10 ventilated ICU patients. Fifty simultaneous measurements were done for heartrate and oxygen saturation and compared to arterial saturations and ECG heartrates...
